How to Convert Poise to Pound-force Seconds per Square Inch
The poise and pound-force second per square inch are both units of viscosity. 1 pound-force second per square inch equals 68947.57 poise. This means to convert poise to pound-force seconds per square inch, you divide by 68947.57.
Formula
Step-by-Step Example
Convert 5 P to pound-force seconds per square inch:
We need to convert poise to pound-force seconds per square inch
Since 1 lbf·s/in² = 68947.57 P, divide by 68947.57
5 ÷ 68947.57 = 7.2518871949e-5
5 P = 7.2518871949e-5 lbf·s/in²

About These Units
Poise (P)
The poise (P) is the CGS unit of dynamic viscosity equal to 0.1 Pa·s or 100 centipoise. Named after Jean Léonard Marie Poiseuille who studied blood flow. Water is 0.01 P, glycerin is ~15 P at 20°C. One poise = 1 g/(cm·s) = 1 dyn·s/cm².
Pound-force Second per Square Inch (lbf·s/in²)
Pound-force second per square inch (lbf·s/in²) equals 6,895 Pa·s—very high viscosity scale. Equal to one reyn. Used for extremely viscous materials: pitch, tar, and high-pressure lubricant calculations. Water is only 1.45×10⁻⁷ lbf·s/in².
